Aviation: Carbon Emissions

Asked by Chris HinchliffLabourDepartment for TransportTabled Answered 3 December 2025UIN 95522

The question

To ask the Secretary of State for Transport, regarding aviation decarbonisation, if she will set out the differences in targets, technological approach, and decarbonisation pathways between the JZS and the CBGDP.

Answered by Keir Mather

This Government is progressing a range of measures to support the decarbonisation of the aviation sector, including supporting sustainable aviation fuels, airspace modernisation and the development of low and zero emission aerospace technologies.

The Carbon Budget and Growth Delivery Plan (CBGDP), published in October, sets out the Government’s plan for delivering Carbon Budgets 4 – 6 across the whole economy. The CBGDP complements the 2022 Jet Zero Strategy (JZS), the policy document which sets the approach for the aviation sector to achieve net zero by 2050.

We regularly update our aviation modelling and assumptions used in our analysis when new evidence becomes available, including the pathways to reach net zero emissions by 2050. The modelling used in the CBGDP is taken from the latest wider modelling of aviation, including emissions, out to 2050. Further versions of updated modelling will be used to inform future publications, including analysis for Carbon Budget 7.
